ABSTRACT
This chapter looks at physical vapor deposition (PVD) processes currently used for wear protectors, including coating of ALTIN/DLC/TIALN, TIN, and so on. It also addresses the latest developments in surface-modification methods, various biomaterials, coating materials, and tribological properties. The PVD coating process is mostly employed in biomedical applications because of its bio-compatibility, high hardness, excellent corrosion resistance, and inertness without changing the biomechanical properties of the substrate, and the film layer is dense and uniform. CP titaniums are known for their excellent corrosion resistance and biocompatibility. As a result, there are attributes that define the surface properties of materials to determine if they are suitable for biomedical application, such as biocompatibility, mechanical properties, tribological features, and osseointegration, to name a few. The combination of these multilayers will be a coating with good qualities such as a low friction, low wear rate, specific chemical protection, and strong corrosion resistance with good biocompatibility.
